Abstract

Endoscopic ultrasonography (EUS)-guided laser ablation (LA) is potentially applicable to tumours in the left lobe of the liver and pancreas. This report seeks to introduce the novel use of EUS-guided LA for left adrenal metastases from pancreatic adenocarcinoma. A 70-year-old female was referred to our hospital for dull abdominal pain and tiredness for 1 month. Computed tomography (CT) discovered a 1.0 × 1.7 cm mass in the area of the left adrenal gland. The lesion was highly suspicious for metastasis due to her history of pancreatic adenocarcinoma 1 year ago, which was removed through radical surgery. Intraoperative frozen-section pathology revealed a tumour invading the left adrenal gland. The left adrenal mass was clearly visualised on EUS and exhibited irregular hyper-enhancement during contrast. The tumour was successfully treated by four sessions of EUS-guided LA. After the procedure, symptomatic relief was achieved and remained. At the 4-month follow-up, contrast-enhanced CT revealed that the volume of the target was significantly decreased. Here, we introduced a new method for left adrenal metastasis using thermal ablation through EUS. As a potential alternative access to the percutaneous approach, EUS-guided LA may provide a minimally invasive treatment to relieve the tumour burdens and symptoms when applied accurately.
